Apologies if I'm mistaken on what you mean but I have the official BG-E6 on my MkII and it definitely has a focus point selector. Far-right button, white cross-hair, same as on the body. About the only Canon accessory I did get and then only 'cos it was thrown half price when I bought the body.
Official accessories take the pee, £150 for Canon intervalometer when you can get a Chinese knock-off for £20, license to print money!
I was actually talking about that little joystick. Which, even the 1Ds mark III didn't have in portrait orientation. As far as I know, only the 1Dx and the 5DIII grip have those.
Oh, I have a lot of Chinese products in my arsenal. But it was always after reading tons of reviews of the product...for this particular product, couldn't find much reviews. That said, the Pixel triggers are very well known for their quality, so not sure this'll be much different.
